Trying to get a 318 to 300+ Horsepower

I have a stock 318 out of a 70-71 Barracuda. Approximately what is the horsepower and torque? And what would be the best way to get it to around 300 hp or more? It's a street car and it may go into my 1968 Dodge Dart. I found some parts for sale locally so... Would a 340 cast iron intake and a 3310 750 holley carb work with some 340 exhaust manifolds? Or should I go for a TQ iron intake manifold for a 318/360? Would the Holley 750 even fit either intake manifold? Thank you  Laugh  
You can't plan a budget for a restoration if you have no money to budget.

I would just like some advice. I'm just trying to learn more about mopars so I may have a successful restoration some day.

750 cfm anything is probably too big for a mild 318. I think you need to look in the 600-650 cfm range.

You can't put a TQ on a Holley-style (4 holes, all same size)  manifold without an adapter, and vice-versa. Personally, I'd prefer a 600 Holley or Edelbrock carb on an aluminum dual-plane manifold.

If you can find some real 340 HP exhaust manifolds, they are good for a 300 HP motor.

318 Performer intake with Holley 600 CFM carb, mild 340 automatic cam, & headers will get you over the 300 HP mark.
Good Luck

Thank you. I'm not sure if the exhaust manifolds are a 340 HP but I found a local listing and the guy is selling them for $400. They have the numbers, "2863549" then under that, "2" and under that, "TI259" i think.
